Two-piece carbon steel coupling with 25 mm round bores, 45 mm outside diameter, 75 mm length

Ruland Manufacturing

Ruland MSPX-25-25-F Two-Piece Coupling 25 mm Bore

SKU CH-M7EF-2VCSN

Two-piece carbon-steel shaft coupling with 25 mm round bores, 45 mm outside diameter and 75 mm length, rated for 400 N-m torque at 4,000 RPM

  • Two-piece design allows easy installation without shaft removal
  • 25 mm bore fits standard shaft sizes for direct connection
  • Carbon steel construction handles up to 400 N-m torque
  • 45 mm outside diameter suits compact machinery layouts
  • Rated for 4,000 RPM maximum speed in power transmission

Rigid Two-Piece Coupling, 25 mm Bore

This carbon-steel coupling joins two 25 mm round shafts in a rigid connection. The two-piece split design allows installation without moving either shaft axially. It transmits up to 400 N-m of torque at speeds up to 4 000 RPM.

Suited for Inline Shaft Alignment.

Builders needing a solid, backlash-free link between aligned shafts will find this coupling effective. Applications requiring angular, parallel or axial misalignment compensation should consider flexible or jaw-type couplings instead.

Fits 25 mm Shafts, 45 mm OD, 75 mm Length

The coupling requires a 51.5 mm clearance diameter around the shafts and adds 75 mm to the overall driveline length. Ensure the surrounding structure accommodates the 45 mm outside diameter and that both shafts are precisely aligned before tightening.

Questions about this item

What shaft diameter must I already have for the 25 mm bore to fit?

Both shafts must be exactly 25 mm in diameter because the coupling has a minimum and maximum bore of 25 mm with no keyway.

Will the 45 mm outside diameter and 75 mm overall length clear the adjacent components I keep?

The coupling measures 45 mm across and 75 mm long, so check that surrounding brackets or guards allow at least that envelope.

How can I confirm the two-piece clamp is transmitting torque correctly after installation?

Run the shaft up to the rated 4,000 RPM and verify no slippage occurs under the 400 N-m torque limit while the coupling remains rigid.
